Tarlac River
The Tarlac River is a river in Central Luzon Philippines, it is the longest tributary of the Agno River with a total length of covering a drainage area of traversing the provinces of Tarlac and Pangasinan. The river originates around the vicinity of Mount Pinatubo and empties itself into the Agno River at Poponto Swamp located between the boundaries of Tarlac and Pangasinan. It was formerly the site of traditional balsa or bamboo raft riding, until the river was heavily silted by sticky lahar or mud flow brought by the eruption of Mount Pinatubo on June 15, 1991, filling the river with over of lahar. Its main tributary is the O'Donnel River in Santa Lucia, Capas, Tarlac. The Tarlac River is dammed at Barangay Tibag in Tarlac City where its water is used for irrigation and distributed to the northern and central regions of Tarlac, the rest of the river is now a bed of sand. The river was once a good source of fish and water used for irrigation, the irrigation system now takes ...

Tarlac City
Tarlac City, officially the City of Tarlac ( pam, Lakanbalen ning Tarlac; pag, Siyudad na Tarlac; ilo, Siudad ti Tarlac; fil, Lungsod ng Tarlac ), is a 1st class component city and capital of the province of Tarlac, Philippines. According to the 2020 census, it has a population of 385,398 people. The city was proclaimed as a highly urbanized city by the former President Gloria Macapagal Arroyo, but the decision was opposed by the provincial government. History Tarlac's first settlers came from Bacolor, Pampanga. They cleared the area, fertilised the soil, and then established their settlement here in 1788. This small community of settlers experienced rapid population growth, as settlers from Bataan, Pampanga and Zambales moved into the area. The Kapampangan language, which is the dialect of Pampanga, became the native language of this town. Roads and barrios were built over the following decades through hard work of its residents. Following the foundation of the provinc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

River Rapids Ride
A river rapids ride (or river rafting ride) is an amusement ride that simulates whitewater rafting. History The river rapids ride concept was proposed by Bill Crandall (general manager of AstroWorld in Houston) and developed by Intamin. AstroWorld introduced the world's first river rapids ride, Thunder River, in 1980 and popularized a concept which can now be found at most major amusement parks. Despite being an incredibly popular attraction, AstroWorld's Thunder River (being a prototype) was initially plagued by issues that were corrected in the first few seasons of operation. The boat bumpers were re-designed, portions of the wide river channel were narrowed or barricaded to prevent boats from bottle-necking or getting caught in a backflow, and a planned whirlpool effect was scrapped. Construction Many modern river rapids rides feature a much narrower river channel as well as smaller boats (6 seats as opposed to 12 seats). Some are heavily themed, while others may present a ...

River Bed
A stream bed or streambed is the bottom of a stream or river (bathymetry) or the physical confine of the normal water flow (channel). The lateral confines or channel margins are known as the stream banks or river banks, during all but flood stage. Under certain conditions a river can branch from one stream bed to multiple stream beds. A flood occurs when a stream overflows its banks and flows onto its flood plain. As a general rule, the bed is the part of the channel up to the normal water line, and the banks are that part above the normal water line. However, because water flow varies, this differentiation is subject to local interpretation. Usually, the bed is kept clear of terrestrial vegetation, whereas the banks are subjected to water flow only during unusual or perhaps infrequent high water stages and therefore might support vegetation some or much of the time. The nature of any stream bed is always a function of the flow dynamics and the local geologic materials, influ ...

Barangay
A barangay (; abbreviated as Brgy. or Bgy.), historically referred to as barrio (abbreviated as Bo.), is the smallest administrative division in the Philippines and is the native Filipino term for a village, district, or ward. In metropolitan areas, the term often refers to an inner city neighborhood, a suburb, or a suburban neighborhood or even a borough. The word ''barangay'' originated from ''balangay'', a type of boat used by a group of Austronesian peoples when they migrated to the Philippines. Municipalities and cities in the Philippines are politically subdivided into barangays, with the exception of the municipalities of Adams in Ilocos Norte and Kalayaan in Palawan, with each containing a single barangay. Barangays are sometimes informally subdivided into smaller areas called ''purok'' ( en, "wikt:zone, zone"), or barangay zones consisting of a cluster of houses for organizational purposes, and ''sitios'', which are territorial enclaves—usually rural—far from t ...

Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow Crop, crops, Landscape plant, landscape plants, and Lawn, lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irri ...

Capas
Capas, officially the Municipality of Capas ( pam, Balen ning Capas; tgl, Bayan ng Capas), is a 1st class municipality in the province of Tarlac, Philippines, and one of the richest towns in the province. The town also consists of numerous subdivisions and exclusive villages. Capas is being dubbed as the “Tourism Capital of Tarlac." Apart from being known as the final site of the infamous Bataan Death March, it is also known for Mount Pinatubo treks, where thousands of mountaineers and visitors go. The town has some industrial factories like the PilMiCo. History Originally a part of Zambales and Pampanga, its first settlers were the Kapampangan and the Aeta. It was founded in the year 1710 by the Augustinian Friars. During the American Colonial period, the Americans built the Camp O'Donell for military installation until when the Japanese used it as a concentration camp during the Bataan Death March as the last stop of the march. Capas as all other towns in Tarlac provi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...

Volcanic Eruption
Several types of volcanic eruptions—during which lava, tephra (ash, lapilli, volcanic bombs and volcanic blocks), and assorted gases are expelled from a volcanic vent or fissure—have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series. There are three different types of eruptions: * Magmatic eruptions are the most well-observed type of eruption. They involve the decompression of gas within magma that propels it forward. * Phreatic eruptions are driven by the superheating of steam due to the close proximity of magma. This type exhibits no magmatic release, instead causing the granulation of existing rock. * Phreatomagmatic eruptions are driven by the direct interaction of magma and water, as opposed to phreatic erup ...

Lahar
A lahar (, from jv, ꦮ꧀ê¦ê¦²ê¦‚) is a violent type of mudflow or debris flow composed of a slurry of pyroclastic material, rocky debris and water. The material flows down from a volcano, typically along a river valley. Lahars are extremely destructive: they can flow tens of metres per second, they have been known to be up to deep, and large flows tend to destroy any structures in their path. Notable lahars include those at Mount Pinatubo and Nevado del Ruiz, the latter of which killed thousands of people in the town of Armero. Etymology The word ''lahar'' is of Javanese origin. Berend George Escher introduced it as a geological term in 1922. Description The word ''lahar'' is a general term for a flowing mixture of water and pyroclastic debris. It does not refer to a particular rheology or sediment concentration. Lahars can occur as normal stream flows (sediment concentration of less than 30%), hyper-concentrated stream flows (sediment concentration between 30 and 60% ...

Siltation
Siltation, is water pollution caused by particulate terrestrial clastic material, with a particle size dominated by silt or clay. It refers both to the increased concentration of suspended sediments and to the increased accumulation (temporary or permanent) of fine sediments on bottoms where they are undesirable. Siltation is most often caused by soil erosion or sediment spill. It is sometimes referred to by the ambiguous term "sediment pollution", which can also refer to a chemical contamination of sediments accumulated on the bottom, or to pollutants bound to sediment particles. Although "siltation" is not perfectly stringent, since it also includes particle sizes other than silt, it is preferred for its lack of ambiguity. Causes The origin of the increased sediment transport into an area may be erosion on land or activities in the water. In rural areas, the erosion source is typically soil degradation by intensive or inadequate agricultural practices, leading to soil eros ...

River Mouth
A river mouth is where a river flows into a larger body of water, such as another river, a lake/reservoir, a bay/gulf, a sea, or an ocean. At the river mouth, sediments are often deposited due to the slowing of the current reducing the carrying capacity of the water. The water from a river can enter the receiving body in a variety of different ways. The motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, and any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface. The river water will then either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is typically the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow.
